This application claims the benefit of U.S. Provisional Application 61/945,197, filed on Feb. 27, 2014, which is incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The present invention is directed to quinoline derivatives, pharmaceutical compositions containing said derivatives and their use in the treatment of disorders and conditions mediated by the CB-1 receptor; more particularly, in the treatment of disorders and conditions responsive to inverse agonism of the CB-1 receptor. For example, the compounds of the present invention are useful in the treatment of metabolic disorders.

BACKGROUND OF THE INVENTION

Centrally penetrant cannabanoid-1 receptor (CB1) inverse agonist compounds are efficacious for weight loss, glycemic control and treatment of cardiovascular risk factors associated with obesity and/or Type II diabetes mellitus. However such compounds are also associated serious adverse effects such as anxiety, depression, suicidal ideation, and others, which adverse effects preclude their use. Peripherally restricted cannabanoid-1 receptor (CB1R) inverse agonists aim to selectively inhibit the CB1R in organs/tissues outside the blood-brain barrier, for example in the liver, adipose tissue and/skeletal muscle, to avoid the adverse effects.

Thus there remains a need for peripherally restricted cannabanoid-1 receptor (CB1R) inverse agonists for the treatment of, for example metabolic disorders, such as obesity, Type II diabetes mellitus, Syndrome X.

One skilled in the art will further recognize that, in the specification and claims as presented herein, wherein a reagent or reagent class/type (e.g. base, solvent, etc.) is recited in more than one step of a process, the individual reagents are independently selected for each reaction step and may be the same or different from each other. For example wherein two steps of a process recite an organic or inorganic base as a reagent, the organic or inorganic base selected for the first step may be the same or different than the organic or inorganic base of the second step. Further, one skilled in the art will recognize that wherein a reaction step of the present invention may be carried out in a variety of solvents or solvent systems, said reaction step may also be carried out in a mixture of the suitable solvents or solvent systems. Examples of suitable solvents, bases, reaction temperatures, and other reaction parameters and components are provided in the detailed descriptions which follow herein. One skilled in the art will recognize that the listing of said examples is not intended, and should not be construed, as limiting in any way the invention set forth in the claims which follow thereafter.

As used herein, unless otherwise noted, the term “aprotic solvent” shall mean any solvent that does not yield a proton. Suitable examples include, but are not limited to DMF, 1,4-dioxane, THF, acetonitrile, pyridine, dichloroethane, dichloromethane, MTBE, toluene, acetone, and the like.

As used herein, unless otherwise noted, the term “leaving group” shall mean a charged or uncharged atom or group which departs during a substitution or displacement reaction. Suitable examples include, but are not limited to, Br, Cl, I, mesylate, tosylate, and the like.

During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.

As used herein, unless otherwise noted, the term “nitrogen protecting group” shall mean a group which may be attached to a nitrogen atom to protect said nitrogen atom from participating in a reaction and which may be readily removed following the reaction. Suitable nitrogen protecting groups include, but are not limited to carbamates—groups of the formula —C(O)O—R wherein R is for example methyl, ethyl, t-butyl, benzyl, phenylethyl, CH₂═CH—CH₂—, and the like; amides—groups of the formula —C(O)—R′ wherein R′ is for example methyl, phenyl, trifluoromethyl, and the like; N-sulfonyl derivatives—groups of the formula —SO₂—R″ wherein R″ is for example tolyl, phenyl, trifluoromethyl, 2,2,5,7,8-pentamethylchroman-6-yl-, 2,3,6-trimethyl-4-methoxybenzene, and the like. Other suitable nitrogen protecting groups may be found in texts such as T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991.

Where the processes for the preparation of the compounds according to the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation with an optically active acid, such as (−)-di-p-toluoyl-D-tartaric acid and/or (+)-di-p-toluoyl-L-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column.

Additionally, chiral HPLC against a standard may be used to determine percent enantiomeric excess (% ee). The enantiomeric excess may be calculated as follows [(Rmoles−Smoles)/(Rmoles+Smoles)]×100%

where Rmoles and Smoles are the R and S mole fractions in the mixture such that Rmoles+Smoles=1. The enantiomeric excess may alternatively be calculated from the specific rotations of the desired enantiomer and the prepared mixture as follows: ee=([α-obs]/[α-max])×100.

The present invention includes within its scope prodrugs of the compounds of this invention. In general, such prodrugs will be functional derivatives of the compounds which are readily convertible in vivo into the required compound. Thus, in the methods of treatment of the present invention, the term “administering” shall encompass the treatment of the various disorders described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.

The present invention further comprises pharmaceutical compositions containing one or more compounds of formula (A) and/or one or more compounds of formula (B) and/or one or more compounds of formula (I) and/or one or more compounds of formula (II) and/or one or more compounds of formula (III) and/or one or more compounds of formula (IV) with a pharmaceutically acceptable carrier. Pharmaceutical compositions containing one or more of the compounds of the invention described herein as the active ingredient can be prepared by intimately mixing the compound or compounds with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral). Thus for liquid oral preparations such as suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, stabilizers, coloring agents and the like; for solid oral preparations, such as powders, capsules and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Solid oral preparations may also be coated with substances such as sugars or be enteric-coated so as to modulate major site of absorption. For parenteral administration, the carrier will usually consist of sterile water and other ingredients may be added to increase solubility or preservation. Injectable suspensions or solutions may also be prepared utilizing aqueous carriers along with appropriate additives.

To prepare the pharmaceutical compositions of this invention, one or more compounds of the present invention as the active ingredient is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration, e.g., oral or parenteral such as intramuscular. In preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed. Thus, for liquid oral preparations, such as for example, suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like; for solid oral preparations such as, for example, powders, capsules, caplets, gelcaps and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be sugar coated or enteric coated by standard techniques. For parenterals, the carrier will usually comprise sterile water, through other ingredients, for example, for purposes such as aiding solubility or for preservation, may be included. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed. The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful and the like, an amount of the active ingredient necessary to deliver an effective dose as described above. The pharmaceutical compositions herein will contain, per unit dosage unit, e.g., tablet, capsule, powder, injection, suppository, teaspoonful and the like, of from about 0.01 mg to about 1000 mg or any amount or range therein, and may be given at a dosage of from about 0.01 mg/kg/day to about 300 mg/kg/day, or any amount or range therein, preferably from about 0.1 mg/kg/day to about 50 mg/kg/day, or any amount or range therein, preferably from about 0.5 mg/kg/day to about 15 mg/kg/day, or any amount or range therein. The dosages, however, may be varied depending upon the requirement of the patients, the severity of the condition being treated and the compound being employed. The use of either daily administration or post-periodic dosing may be employed.

Preferably these compositions are in unit dosage forms such as tablets, pills, capsules, powders, granules, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, autoinjector devices or suppositories; for oral parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. Alternatively, the composition may be presented in a form suitable for once-weekly or once-monthly administration; for example, an insoluble salt of the active compound, such as the decanoate salt, may be adapted to provide a depot preparation for intramuscular injection. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from about 0.01 mg to about 1,000 mg, or any amount or range therein, of the active ingredient of the present invention. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of material can be used for such enteric layers or coatings, such materials including a number of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, aqueous solutions, suitably flavoured syrups, aqueous or oil suspensions, and flavoured emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone or gelatin.

The method of treating disorders described herein may also be carried out using a pharmaceutical composition comprising any of the compounds as defined herein and a pharmaceutically acceptable carrier. The pharmaceutical composition may contain between about 0.01 mg and about 1000 mg of the compound, or any amount or range therein; preferably from about 1.0 mg to about 500 mg of the compound, or any amount or range therein, and may be constituted into any form suitable for the mode of administration selected. Carriers include necessary and inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings. Compositions suitable for oral administration include solid forms, such as pills, tablets, caplets, capsules (each including immediate release, timed release and sustained release formulations), granules, and powders, and liquid forms, such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions and suspensions.

Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when desired or necessary, suitable binders; lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include, without limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like.

The liquid forms may contain suitably flavored suspending or dispersing agents such as the synthetic and natural gums, for example, tragacanth, acacia, methyl-cellulose and the like. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.

To prepare a pharmaceutical composition of the present invention, a compound of formula (I) as the active ingredient is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration (e.g. oral or parenteral). Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers may be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.

Biological Assays

CB₁ and CB₂ receptors are G_(i)-coupled GPCR. Activation of CB₁ and CB₂ receptors results in a decrease in cAMP production. An inverse agonist of the CB₁ or CB₂ receptor results in the opposite effect, an increase of cAMP production. The principle of this assay is based on HTRF® technology (Homogeneous Time-Resolved Fluorescence). The method is a competitive immunoassay between native cAMP produced by cells and the cAMP labeled with the fluorophore d2. The tracer binding is quantified by a Mab anti-cAMP labeled with Eu3+TBP-NHS Cryptate (supplied as part of the assay kit). The specific signal (i.e. energy transfer) is inversely proportional to the concentration of cAMP in the standard or sample.

Biological Example 1 CB-1 and CB-2 In Vitro Assay

Preparation of Cells

Human CB₁R (Cannabinoid receptor 1) was stably transfected in HEK-293 cells (DiscoveRx, cat: 93-0200C1). Human CB₂R (Cannabinoid receptor 2) was stably transfected in HEK-293 cells (DiscoveRx, cat: 93-0201C1). Cell cultures were maintained in media: DMEM (Invitrogen Cat#12430-054) supplemented with 10% HI FBS (Invitrogen Cat#16140-071), 1% L-glutamine (Invitrogen Cat#25030-081), 0.2 mg/ml Hygromycin B (Invitrogen Cat#10687-010), 600 μg/mL G418 (Invitrogen Cat#10131-035), and 1X Penn/Strep (Invitrogen 15140-122). After cell expansion, aliquots were cryo-stored in media containing 5% DMSO (Pierce Cat#20684).

Plating Cells from Cryostore

One day prior to experiments media was warmed to 37° C. and the cryo-stored cells were thawed in a 37° C. water bath. The cells were then added to media (10× volume) and the mixture was centrifuged at 1000 RPM for 5 min. The supernate was removed and the cells were re-suspended in media. A sample of the cell suspension was evaluated on a Cedex XS automated cell counter (Innovatis Systems) to determine viable cells/ml. Additional media was added to the cells to achieve a final cell density of 4E5 cells/mL. The cells were then plated into 384 well PDL white solid bottom plates (Greiner, Cat#781945) at 20 μL per well using a Multidrop (Thermo Scientific). Cells were removed from Row P (location of cAMP standards). Two columns of cells were plated into a clear bottom 384 well PDL coated plate (Greiner, Cat#781944) to view confluence the day of the assay. The cell plates were lidded and stored for 15 minutes in a hood, then transferred to an incubator (37° C., 5% CO₂, 95% humidity) overnight.

Preparation of Compound Plates

DMSO was added to all wells of 384 well V bottom polystyrene plate (Greiner, Cat#781280) except to columns 1 and 13, rows 0 and P and wells M13-M23 and N13-N23. Test compounds (60 μL, 10 mM) were added to Column 1 and 13 (A1 through N1 and A13 through L13). Test compounds were serially diluted 1/3 by transferring and mixing 20 μl sample with 40 μL DMSO. This process resulted in a plate of 26 compounds, 11 doses per compound, 10 mM to 0.5 μM.

Preparation of Control Plate

DMSO (40 μL) was added to wells of 384 well V bottom polystyrene plate: O2 through O11, M14 through M23, N14 through N23, and O14 through O23. AM630 (also known as [6-iodo-2-methyl-1-[2-(4-morpholinyl)ethyl]-1H-indol-3-yl](4-methoxyphenyl)-methanone, Cayman Chemical, Cat#10006974) (60 μL, 10 mM) was added to 01; and 1-(2,4-dichlorophenyl)-7-[(4-fluorophenyl)methylene]-4,5,6,7-tetrahydro-N-1-piperidinyl-1H-indazole-3-carboxamide (60 μL, 10 mM) was added to N13. The control was serially diluted 1/3 by transferring and mixing 20 μl sample with 40 μL DMSO. This process resulted 11 doses per control, 10 mM to 0.5 μM.

cAMP Assay Protocol

Cells plated the day prior to the assay in clear bottom plates were viewed on an inverse microscope to ensure confluency in the range of 60-75%.

The following mixtures and buffer solutions were prepared: (a) Buffer 1: HBSS (Mediatech Cat#21-023-CV) with 5 mM HEPES (1 mM stock, Gibco BRL Cat#15630-056) and 0.1% BSA (7.5% stock, Invitrogen Cat#15260-037); (b) Buffer 2: 0.5 mM IBMX (200 mM stock in DMSO, Sigma 15879) in Buffer 1; (c) 1 μM cAMP Standard (50 μM stock, Perkin Elmer Cat# AD0262) diluted in Buffer 2 and serially diluted in Buffer 2, 12 doses @ ½ dilutions resulting in a dose range of 1 μM to 0.5 nM; (d) d2 labelled cAMP (CisBio HTRF Detection Kit Cat #62AM4PEB reconstituted with 6 ml dH₂O) diluted 1/20 with lysis buffer (CisBio HTRF Detection Kit Cat #62AM4PEB); (e) anti-cAMP (CisBio HTRF Detection Kit Cat #62AM4PEB reconstituted with 5 ml dH₂O) diluted 1/20 with lysis buffer (CisBio HTRF Detection Kit Cat #62AM4PEB); and (f) Forskolin (Sigma Cat# F6886, 10 mM in DMSO) diluted first in DMSO to 1 mM and then to 1.5 μM in Buffer 2.

A FLEXDROP (Perkin Elmer) was cleaned with ethanol then water, and primed with Buffer 2. A 384 well V bottom polypropylene plate containing d2 labelled cAMP and a second 384 well V bottom polypropylene plate containing anti-cAMP was prepared (50 μl per well). Media as “dumped” from the cell plate and 30 μL Buffer 1 was added to each well using a Multidrop. The content of the cell plate was again “dumped” and 10 μL Buffer 2 was added to each well using a Flexdrop. 12.5 nL test compound dilutions or control compound dilutions (10 mM to 0.5 μM) were added to the cell plate using an ECHO 555 (Labcyte). The cell plate was mixed (Speed 6, Lab-Line Instruments Titer Plate Shaker) and centrifuged (1000 RPMs, 1 min). Using the Flexdrop, 2 μl additions were made into the cell plate: Buffer 2 was added to Column 24; and, 1.5 μM Forskolin was added to columns 1 through 23. Final volume of the cell plate was 12 μl with 250 nM Forskolin in all wells except column 12, and serial dilutions of test compound or control ranging from 10 μM to 0.5 nM. The cell plate was again mixed (speed 6) and centrifuged (1000 RPMs, 1 min). The cell plate was incubated for 30 minutes at room temperature (˜27° C.). The contents of row P were removed and the cAMP standard dilutions were added in duplicate to Row P (P1-12 and P13-24). After incubation, 6 μL d2 labelled cAMP and 6 μL of Anti-cAMP were added to all wells of the cell plate using a BioMek FX (Beckman Coulter). The cell plate was again mixed (speed 6) and centrifuged (1000 RPMs, 1 min) and was incubated for 60 minutes in the dark at room Temp (˜27° C.).

After this final incubation, the cell plate was read in HTRF mode (fluorescence at 665 nm and 620 nm) on an Envision plate Reader (Perkin Elmer). The Envision reader outputs a ratio of channel 1/channel 2 fluorescence×10,000 (Normalized signal (NS)). Amount of cAMP in nM was calculated for each well (based on NS) from a cAMP standard curve located on each plate (at P1-12 and P13-24). EC₅₀ values were determined from a 4-point fit (Hill equation) of a single 11-point compound dosing. Hill slope was fixed at 1.0. The bottom of the dose response curve was fixed because it was always the same as that of the control wells containing vehicle (DMSO) instead of compound. The top of the dose response curve was floated unless a plateau was not reached.

Biological Example 2 CB-1 & CB-2 Receptor Binding Assay

Experimental Procedure CB-1 Membrane Binding:

Into Greiner V bottom polypropylene plates, hCB1-CHO-K1 membranes (2 μg/well final concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl₂ and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) were dispensed. Membranes were purchased from Perkin Elmer. Test compounds were then added to each well and then [³H] CP 55, 940 (0.4 nM final well concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl₂ and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) was added. Samples were mixed and incubated for 90 min at 30° C. in the Greiner V Bottom Polypropylene plate. After incubation, assay reagents were transferred to a blocked 384 well polypropylene filter plates. The binding reaction was stopped by filtration and washed seven times with ice cold rinse buffer. Filter plates were then dried overnight at room temperature. The next day, plate bottoms were sealed with plate tape and 15 μl MicroScint 20 was added to each well. Plates were incubated for 2 h and radioactivity was measured by Topcount.

Experimental Procedure CB-2 Membrane Binding:

Into Greiner V bottom polypropylene plates, hCB2-HEK293 membranes (2 μg/well final concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl₂ and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) were dispensed. Membranes were prepared as described in FELDER, C. C., et al., Molecular Pharmacology, 1992, pp 838-845, Vol. 42. Test compounds were then added to each well and then [³H] CP 55, 940 (0.5 nM final well concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl₂ and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) was added. Samples were mixed and incubated for 90 min at 30° C. in the Greiner V Bottom Polypropylene plate. After incubation, assay reagents were transferred to a blocked 384 well polypropylene filter plates. The binding reaction was stopped by filtration and washed nine times with ice cold rinse buffer. Filter plates were then dried overnight at room temperature. The next day, plate bottoms were sealed with plate tape and 15 ul MicroScint 20 was added to each well. Plates were incubated for 2 h and radioactivity was measured by Topcount.

Total Binding:

Total Binding levels were achieved by combining membrane, DMSO, and [³H] CP-55,940 (also known as 5-(1,1-dimethylheptyl)-2-[(1R,2R,5R)-5-hydroxy-2-(3-hydroxypropyl)cyclohexyl]-phenol).

Non-Specific Binding (NSB):

Non-Specific Binding (NSB) levels were achieved by combining membrane, 10 μM final concentration WIN-55,212 (also known as (R)-(+)-[2,3-Dihydro-5-methyl-3[(4-morpholinyl)methyl]pyrrolo[1,2,3-de]-1,4-benzoxazinyl]-(1-naphthalenyl)methanone mesylate, Tocris Biosciences Cat#1038), and [³H] CP-55,940 (also known as 5-(1,1-dimethylheptyl)-2-[(1R,2R,5R)-5-hydroxy-2-(3-hydroxypropyl)cyclohexyl]-phenol).

Data Analysis:

Top Count raw data files were used for data analysis as follows:

Non-specific binding (NSB=10 μM WIN-55,212+Membrane+[³H] CP-55,940) was used as the negative control, while the Total Binding (TB=DMSO+Membrane+[³H] CP-55,940) was used as the positive control.

Excel data file reports were generated by the PE TopCount and imported into Excel for calculations or were imported into a macro driven Excel template maintained by Lead Generation—Biology.

IC₅₀ data was calculated using raw CPM values. Curves were fitted individually from singlet 11 point dosing curves+1% DMSO Control. IC₅₀ values were fit appropriately and calculated using the following equation:

$v = {V_{\min} + \frac{V_{0} - V_{\min}}{1 + \left( \frac{\lbrack I\rbrack}{{IC}_{50}} \right)^{h}}}$

V_(min), CPM at maximum inhibition; V_(o), CPM at zero inhibition; IC₅₀, inhibitor concentration at 50% inhibition; h, Hill coefficient.

Maximal compound % inhibition of control treated wells was also noted since some compounds exhibited values suitable for calculating IC₅₀'s. % Inhibition of Total Binding=(1−(CPM Compound Treated Well/CPM Control Treated Well))*100

Biological Example 5 Open Field Locomotor Activity in Rats (CNS Activity)

Male SD rats were weighed and transferred to the Activity Chambers with access to water. After a 2-hr acclimation period, the rats were dosed with vehicle or test compound (@ 3 and 10 mg/kg). The Activity Chamber monitoring software program was initiated and automatically recorded rat activity in each chamber for a period of 4 hours. At the end of the 4 hour monitoring period, the software was stopped and the rats were removed from the activity chambers. The rats were anesthetized and blood samples were obtained via retro-orbital puncture to determine plasma concentration of compounds. The rats were immediately euthanized with CO₂ and the brains removed, washed with PBS, frozen on dry ice and stored at −80° C. for receptor occupancy (RO) analysis.

Satellite groups of 3 rats were dosed with test compound at 3 mg/kg and 10 mg/kg respectively. Four hours later, the rats were anesthetized. Blood was collected from these rats and then they were perfused with 400 ml heparinized saline through the left ventricle of the heart. The brains were removed and homogenized in PBS (4 ml/gm tissue). The samples were submitted for determination of plasma and brain compound levels.

Compound #44 was tested in n=8 animals, according to the procedure as described above, with stereotypic counts as listed in Table BIO-5A; and plasma and brain drug levels as listed in Table BIO-5B, below.
